4140 Steel Plate Supplier

4140 grade of steels is a chromium, molybdenum alloy. The 4140 steel plate is low AS designed for excellent corrosion resistance properties. These plates show excellent strength to weight ratio in the system. Aisi 4140 Plates or Chromoly steel exhibits enhanced fatigue strength with good impact and abrasion resistance in stress-induced systems.

The 4140 Plate has exceptional toughness with excellent torsional strength. These plates exhibit an excellent melting point of 1416 degrees C. Designed with enhanced ductility, the 4140 Alloy Steel Plate can be easily formed following standard procedures in annealed conditions. The versatile modules of the 4140 Steel Sheet can be welded using factory welding procedures. If they are heat treated after the welding procedures their mechanical performance will be affected.

Steels is available in different grades. 4140 and 4340 are amongst the commonly used grades of steel. Both these modules have contrasting properties and features.

•   4140 and 4340 have similar traces of sulfur, phosphorus, silicon and molybdenum, and manganese. The carbon content in the 4340 grade is higher, but the content of chromium in the 4140 grade is higher. The major differentiating factor is the presence of nickel in the 4340 grade giving it excellent tolerances in stress-induced systems.
•   The tensile and yield strengths of the 4340 grades are higher than the 4140 grade giving the 4340 grades enhanced strength and performance.

• 4140 is designed to possess a tensile and yield strength of 655mpa and 415mpa, respectively. 1045 grade is designed with a tensile and yield strength of 565mpa and 310mpa, respectively. This gives the 4140 higher strength than the 1045 grade.
• 1045 is designed with a chemical composition of carbon, iron, manganese, phosphorus, and sulfur. 4140 grade is designed with a chemical composition of chromium, manganese, carbon, silicon, molybdenum, sulfur, phosphorus, and iron. The content of molybdenum and chromium gives the 4140 enhanced corrosion resistance over the 1045 grade.

 

The thickness of a plates influences the weight as well as the strength of the plates. The thickness of the 4140 Plate Stock starts above 6mm and can extend to 100mm or more depending on the requirements of the application. The 4140 Annealed Plates is treated after the initial rolling stage. Plates are generally annealed to increase their ductility to reduce the material's hardness.

4140 Pre Hard Plate is heated to achieve a medium hardness between 28 to 32 HRC. These plates have a thickness between ¼ to 12mm. The 4140 Prehard Plate can be hot rolled or turned with the ground and round polished components having high structural strength. The thickness of the 4140 Ht Plates affects the mechanical properties and the welding capacities of a plates.
